XW110/XW111 WiFi™ Users Manual Intro uction
Section 1: Introduction
The XW110 an XW111 are easy to use wireless Wi-Fi temperature monitoring an status alerting
evices. The XW-110 measures an reports temperature using a temperature probe which contains a
precision igital sensor. The XW-111 monitors an reports the status of switch closure sensors an
alarms. Both are i eal for applications where temperature or events must be monitore an Ethernet
wiring is not accessible or practical to install.
The mo ules are powere from either two internal AA batteries or a 5-volt wall transformer. In the case
both are connecte , the XW11x will use the wall transformer an automatically switch to the batteries in
the event of a power failure. A three position terminal strip provi es connections for a temperature
sensor or up to two switch closure sensors. Not other cables, interfaces or PC utility programs are
nee e .
Two user accessible push button switches ai in provisioning the mo ule. Press the “access point”
switch to active the access point mo e. With a PC or smart phone you then connect to an access the
internal web server. Using the web server, you may configure the measurement interval, access port,
name an other setup parameters. Alternatively, press the WPS (Wi-Fi Protecte Setup) switch on both
the XW11x an your access point to a the XW11x to an existing network.

1.1.3 Wireless Communication otes
Due to the nature of wireless communications, transmission an reception of ata can not be
guarantee . Data may be elaye , have errors or be lost. Although elays or losses of ata are rare
with a well constructe network, ata can be lost ue to interference, noise, reflections or other
environmental con itions. The XW11x shoul not be use in situations where failure to transmit or
receive ata coul result in amage to property, equipment, irect, in irect, consequential, or inci ental
amage (inclu ing amage for loss of business profit, business interruption, loss of ata, life, an the
like.)

Begin by wiring the sensors to the green 3-terminal strip.
2.1.1 XW-110 Temperature Sensor Connections
The XW-110 works with a specific igital temperature sensor which is interchangeable an requires no
calibration. The sensors accuracy is +/-0.5°C (-10°C to +85°C). The sensor requires three connections
for communications an power (+5V, Groun , Data). The temperature sensor is available in several
configurations. For monitoring room temperature, the bare sensor can be connecte irectly to the
terminal strip. The rugge version is encapsulate in a stainless steel probe an can be use in
unprotecte out oor locations.

2.1.2 XW-111 Switch Closure Connections
The XW-111 can sense the state of up to two switch closure sensors. Sensors with switch closure
outputs inclu e push buttons, magnetic oor alarm switches, micro-switches, or any evice which has a
relay or switch closure output. Both sensor inputs share the same GND connection. The XW-111 can be
configure for the alarm to be active when the switch is either open or close . If possible, use switches
which are normally open (NO). When the switch contact is open no current flows thru the switch an the
longest battery life is achieve . When the switch is close 17uA flows thru the switch.
The inputs use 3.3Volt logic an work with simple switches an relays. Do not connect the igital inputs
to a power source. The inputs will work with cable lengths up to 50-feet an shoul not be route near
motors or AC wiring. The connections for two switches are shown:
2.1.3 Power
The XW-110 an XW-111 are powere from either a 5-volt DC wall a apter or two internal 1.5V “AA”
batteries. If the wall a apter is connecte , no power is rawn from the batteries. If the external power
fails the mo ule automatically switches to the internal batteries. No jumpers or switches are nee e .
The wall a apter shoul be use for certain mo es with high current eman s such as: “Stan -Alone
mo e” with HTTP server enable , “Slave mo e” with high reporting rates, or when “access point” is
active.

2.1.4 Provisioning
After making the sensor connections an provi ing power, you must provision the XW11x for use on your
wireless network. The goal is to configure the XW11x such that it can recognize an attach to your Wi-Fi
access point. There are two metho s for oing this:
Internal Web Server
The web server requires an active Wi-Fi connection running at full power. It is recommen e to use a
wall-transformer with this metho or o the configuration quickly as this mo e consumes large amounts
of energy. If this is the first time powering the evice, it will automatically enumerate as an access-point,
other wise, you must remove the top cover an press the “access point” push button. The XW11x will
awaken an begin broa casting as an access point. Its SSID is “TempMo ule-XXXXXX” or
“InputMo ule-XXXXXX” where XXXXXX are the last six igits of its MAC a ress. With your wireless
evice (laptop computer or smart phone) scan for, an attach to the TempMo ule or InputMo ule
wireless network. Next, access the web server in the XW11x using a web browser. To access the setup
pages, enter the following URL in the a ress bar of your web browser:
http://192.168.1.2/setup.html
After the page is requeste , a passwor prompt will appear. Enter the username an passwor . The
efault username is admin an the efault passwor is webrelay (passwor is case sensitive). The
following chapter explains each of the setup tabs an screens. Use the WiFi Networks tab for making
the proper settings to allow the XW11x to connect to your access point.
WPS (Wi-Fi Protected Setup)
The WPS Push button method, allows users a simple metho for attaching the XW11x to a wireless
network without nee ing to use any setup pages. To begin, press the WPS button on your wireless router
or access-point. You will generally have about two minutes to connect wireless evices to the network
with WPS. Now remove the cover of the XW11x an press the “WPS” push button. After a few secon s,
the XW11x shoul register itself with the router or access-point. If the XW11x has not alrea y been
configure , it will use DHCP to obtain an IP a ress. You will nee to access the DHCP server, router, or
access-point to fin the IP a ress it was assigne . A itionally, the connection information is also
broa cast using mDNS. Please note, that the XW11x web server is available with the efault
configuration, but will not be if the evice has been configure as a slave evice or if it has been isable
for the stan -alone mo e.

Section 3: Setup Pages
The XW11x is configure using a web browser. To access the setup pages, enter the following URL in
the a ress bar of a web browser:
http://192.168.1.2/setup.html
If the XW11x has been a e to a network using WPS, it will use DHCP an you will nee to use the IP
a ress assigne to it. This can be foun in the DHCP server, or by using mDNS. The mDNS name is
<NAME HERE>.
3.1 Main Tab – Stand Alone
This is the initial page that is isplaye when setup.html is entere into the a ress bar of the browser. It
isplays mo el an serial number information, an has navigation tabs which allow access to the
configuration an setup settings. The web pages an communication settings for the XW-110 an XW-
111 are similar, pages with specific settings for the temperature or igital inputs are shown in the
following sections.

The XW11x operates in two fun amental mo es esignate “Slave” an “Stand-alone”. Depen ing on
this setting the menu tabs change to reflect the relevant settings. Select “Slave” if the XW11x is to make
measurements an sen ata to a master evice such as an X-600™. Select “Stan -Alone” if the
XW11x is to simply monitor the temperature/inputs an /or sen e-mail alerts.
The Mode setting will not take effect until the XW11x is reboote . To o this click the Reboot button after
making a change to the Mode.
Slave:
•In this low power mo e the XW11x sleeps most of the time. It perio ically awakens, makes
measurements, connects to a WiFi network an transmits ata to a CBW evice or other server.
•Use longer interval for long battery life.
•Intermittently connects to the wireless network as a Station. If the reporting interval is short, the
WR100 remains connecte since the energy require to re-connect is greater than the energy
save by isconnecting.
•No Emails are supporte
•The Alert tab is suppresse , Remote Master tab is shown
•The internal web server is not accessible
Stand-Alone:
•Operates as a Station which allows the XW11x to be part of another wireless network.
•Perio ically makes measurements an sen s email alerts only when alarm con itions are
satisfie .
•Alarms an Emails are supporte .
•The Alert tab is visible an Remote Master is suppresse .
•The internal web server is accessible at the option of the user. Enabling the internal web server
requires an active connection to the access point an is not feasible with battery operation.
Access Point:
•As an Access Point the XW11x functions in epen ently of other wireless networks. It broa casts
beacons an services WiFi packet requests.
•Connect to the XW11x access point with any WiFi enable phone or laptop computer.
•Use for provisioning the XW11x.
•Perio ically makes measurements an isplays the ata on its internal web page. Data is not
sent to other networks.
•Access Point works best when powere from a 5-volt DC wall a apter.
